The replace function is documented here
http://www.w3.org/TR/xpath-functions/#func-replace
Which refers to Regular Expressions here
http://www.w3.org/TR/xpath-functions/#regex-syntax
Which references Unicode Regular Expressions
http://www.unicode.org/reports/tr18/
Which after intense study and getting your PhD in Regular Expressions , you
will find that
\p{ xxx } means "Property xxx" and "L" is for normal letters so \p{L} matches
all normal letters in all unicode sets.
